            A new logging configuration option has been added which
            does not flush the transaction log from the operating
            system cache to stable storage when a transaction commits
            or the logging system switches log files. This can further
            improve performance when all of the applications in an
            environment use less-than-durable transactions
            (<a href="../api_reference/C/envset_flags.html#envset_flags_DB_TXN_NOSYNC" class="olink">DB_TXN_NOSYNC</a> and <a href="../api_reference/C/envset_flags.html#set_flags_DB_TXN_WRITE_NOSYNC" class="olink">DB_TXN_WRITE_NOSYNC</a>).
